I finally decided to give Ruffian 2.1.0 (instead of 2.0.2) a run in YABRL, because it represents the latest in Ruffian development.
After 760 games Ruffian 2.1.0 came out only at a par with Ruffian 2.0.0; hence under the conditions of YABRL there is no measurable increase in playing strength between these two versions. This result is in line with some other results I am aware of, e.g. http://www.geocities.com/chessfun_1999/rating.html, where the difference is also only 11 points (at longer time controls) between the two.
As Ruffian 2.0.2 is a bug fix version of Ruffian 2.0.0 it appears likely that 2.0.2 would probably have done a little bit better than 2.1.0, and would have achieved more than only 2 points "improvement". Maybe I should also run Ruffian 2.0.2 under the same conditions...
Time control is 300+2, for details on conditions, platform and tools please refer to link below.
Next engine is Tao 5.6.
